### DAV Class 4 Maths Chapter 9 Worksheet 7 Notes

Changing Fractions

1. Imprper fractrion into mixed number.

E.g. Change \(\frac{17}{2}\) into mixed number.

Answer:

\(\frac{17}{2}\) can be written as 17 ÷ 2

so \(\frac{17}{2}\) = 8\(\frac{1}{2}\)

2. Mixed number into improper fraction.

E.g. Change 2\(\frac{1}{2}\) into fraction.

Answer:

2\(\frac{1}{3}\) = 2 × 3 = 6

2\(\frac{1}{3}\) = 6 + 1 = \(\frac{7}{3}\)
